KNITTING-MACHINE.

SPECIFICATION forming part of LettersPatent No. 510,760, dated December 1 2, 1893.

Application filed July 18, 1892. Serial No. 440,299. (No nindel.) Patentedin Switzerland June 20,1892, No. 5,580; in Germany June 21,1892, No.71,280; in England June 22,1892, No.11,678; in France June 23,1892,N0.222,555: in Belgium June 23, 1892,N0. 100,260, and in Austria-Hungary May 4, 1893, N0. 32,941 and No. 88,284.

To all whom it may concern:

Be it known that I, AUGUST AUWARTER, a subject of the King of Wiirtemberg, residing at Schlierbach, VViirtemberg, Germany, have invented a certain new and nsefnl Improvement in Knitting-Machines, (for which I have received Letters Patent as follows: in Great Britain June 22,1892, No. 11,678; in

Switzerland June 20, 1892, No. 5,580; in Germany June 21, 1892, No. 71,280; in Austria Hungary, No. 32,941 and No. 88,284, dated May 4, 1893; in France June 23, 1892, No. 222,555, and in Belgium June 23, 1892, No. 100,250,) and I do hereby declare the following to be a full, clear, and exact description of the invention, suchas will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to knitting machines and it consists in certain features, and details of construction whereby a tubular fabric may be made on a straight machine, and, if de-.

sired, a reinforce yarn knit in on any article being made on the machine.

The invention will first be described in connection with the accompanying drawings, and then pointed out in the claims.

In the drawings,.Figure 1 is a side elevation of so much of a straight knitting machine as is necessary to illustrate my invention. Fig. 2 is a plan view of the same. Fig. 3'is a detail view of the single cam. Fig. 4 isa detail View of the double-cam. Fig. 5 is a detail view of the cam-operating device.

Referring to the drawings, 1, are the needle plates,'2, the bed, 3, the crank-rod, and 4, the crank of an ordinary straight knitting machine, the needles and such other devicesas are unnecessary in the explanation of my invention being omitted.

R, is the working-frame carrying a single needle-operating cam, S, on one side and donble needle-operating cams, S and S on the opposite side.

E, is a slide or cam-operating device, which engages with the double-cams, 8 S to open and close the needle race-ways alternately, it being apparent that as one race-way is opened the other will be closed, the slide or cam-operating devicebeing thrown at each end of the stroke by striking against the adjustable stops, 6, as will be plain from Fig. 2. Each cam, S, S has a pin engaging one of the inclined slots of the plate, E.

C is a bolt for operating the block on which the yarn-guide,f is mounted, whereby the yarn-guide will be moved along with the carriage, as will be fully understood from the description and drawing of a similar arrangement shown in Patent No. 471,696, dated May 29, 1892. C and C are similar bolts for engagement with the block on which yarn-guide, f is mounted, these two bolts being alternately engaged with and disengaged from the said block by riding up the inclined edges of the adjustable stops, 0.

The yarn-guides are shown at f and f the front one operating for the rear needle-row and the rear yarn-guide operating for the front needle-row; whereby, by each change of throw, the yarns are crossed, the rear yarn-guide, after each change of throw, again running ahead of the front one. Of the two yarnguides f and f one of them receives a simple knitting yarn, and the other a like yarn together with-the reinforcing yarn.

In Fig.1, the position of the two yarn-guides f and f is shown by full lines at the beginning of the throw toward the right, and by dotted lines at the beginning of the throw toward the left. The yarn-guide, f located above the double-cam, 8 8 which yarn-guide operates for the row of needles actuated by the single cam, S, will always run behind the guide, f which operates for the front row of needles actuated by the double-cam, the forward of the two bolts (For 0 after the change of throw, always bringing the yarn-guide, f to its advance position with respect to the other'yarn-guide. Moreover the single cam is so located opposite the double-cam that one cam of the latter always works in advance of the oppositely-disposed single cam while the other cam of the double-cam is at rest; so that the needles of the advanced portion of the double-cam have already returned to their po- Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a knitting machine, the combination, with the double row of needles and means for supplying yarn to the needles, of a double cam-plate upon one side of the machine, the forward cam normally in engagement with the needles on its respective side, a single cam-plate on the opposite side of the machine, and means for opening one and closing the other cam of the double cam-plate, substantially as described and for the purpose set forth.

2. In a knitting machine, the combination, with the double row of needles, of a double cam-plate upon one side of the machine, and
